WINDOW Vannini/iron.

Application filed November 27, 1926. Serial lNo 151,120. A

. ment so as to be placed withinI a window acter, which is extremelysimple in constlriic- I tion, thoroughly reliable and eilicient in itsframe to permitthe window sash. to be brought in engagement therewith,lwhereby ventilation may be had through the window,

.without liability of the ingress of sleet, rain7 or snow lto theinterior of the enclosure having the window, the adiustment `of theventilator permitting the same tobe adaptable for .various sizes ofwindow frames.

Another object ofthein'vention is the .provision of a ventilator of thischaracter, wherein the saine can be placed .within an openingconstituted' bythe partial raising of the window sash in the -frame andwill. shield such opening to constitute a deflectorv for a draft of airpassing through the opening 'from without to the interior 4of thebuilding.

A ,nu-chef Object. of the invention is the provision of a ventilator ofthis character, wherein the, entirestructure is made from met-al and isunited together in the parts thereof ina novel mannen-so that such partswill vbe'firm and secure and the said ventilator capable ofvaryingadjustment to. adapt Vthe same `to different sizes of thefwndowframes. i l' f A still further object ofthe inventionis the provision ofa ventilatorof this charpurpose,v strong, durable, readily andf easilyYapplied to and removed from a Vwindow frame and inexpensive tomanufacture.

struction, combination and arrangement of' .part-s, as will behereinafter more fully described, in detail, illustrated in theaccompanying drawing, showing the preferred em-v bodiment of theniveiition and pointed out v in the claims-hereunto appended.

Referring to ther drawing 'in fdetail,` A

designates generally a portion of a window' frame, which is of therconventionaltype.y

respectively, carried by each side of the window framei between its sill12 andthe head of said-frame, the headybeing noti"V sliowinv vfll-id'apted'to be reinovablyand adjustably f vh'eldgwitliin thewindowrframe is the ventilator constituting the present inventioin'which willv be, hereinafter more fiillyf described in detail.v L 'y i.

Thejventilator comprises apai'r fof telefscopically connectedextensiblev sections 13 and'l 14E",v respectively, each being formedwithV yso a' lower bottom iplate p15-and anupperor top head plate 167both beingformed from vlith these and'y other objects in view,v theinvention consists in the..features of con-v sheet metal. rl`he outerends of these sections V13 and 14 have the.. lowerv and upper plates 15and 16'are spacedapart 'and have" ticulated or-wiremesh fabric 19.1eachbeing engaged at its inner end in afolded-over end strip 2O and atthe opposite longitudinal :10o arranged tocovorgsuch space screensorre-v edges by folded-over longitudinally `extending border strips 21,while'the, `outer end .edge of the fabric 19 is foldedin with the outerend strip 17, connecting the plates' and 16 together. The strips 20 and21 are fastened to the plates v15 and 16 Vthrough the medium ofsplitrivets 22, While linkedito the outer strip 17 of each extensiblesection and riveted to the fabric 19 is a reinforcing strip 23. Thefabrics 19 constitute the ven1 t-ilatingpanels of the sections 13V and14 asl will be apparent.

outer spaces of the sections 13 'and-141 so as nottointeri'ere with theextension of the` sections when. telesco'pically connected in relationto each other. Thetop plates 16y of tlresec'tionsv 13 land 14 areextended to provide angularly disposed awning-like Vshields 24 andv25,"respectively,'having the straight free end portions 26 disposedparallel with the plane of the sections 13 vand but spaced 'a distancetherefrom and held 1n such spaced relation 'by-the braces 27 connectedthereto and to 'the sections 13 and- 14, re-

. spectively. y

The section 14' has its bottom plate 15` and the Canopy exteitlsion'25ybent on themselves to provide the guide flanges 28 and 29,1'espectively,to provide rufnWays for the edges of 'the extensions of the bottomplates 15 and the extensions 24 "of the other section 13.

n and in' this' manner these sections 1.3 and yau 14 4are slidablyconnected with a unitary structure. I

The 'canopy extensions 24 and 25 overhang Ventilating *panels 19 of thesections 13 fand 14 and the canpy extensions terminate 4a distance abovelorffrom the free edges `of vtil-1e bottom iplates 15 of the sections 13and or'm an air way as indicated by the arrows in Figures 1 and 6 of thedrawing for ventilatirg purposes Jto admit Vair y from Without `Will bepositioned either as shown in Fig? lure l or vFigure of the drawing.When positioned ving the `ventilator will shield sleet, rain, or

1 VInt-he use of the ventilator the sections 13 and 14 are extendedrelative to `eachother so 'that 'their outer ends will engagebetween theguide strips 10 and 11 of thewindow frame A and the canopy extensions 24and asshoW-n in 'Figure 1 Vof the drawvthe sash B is brought against"the same at .Y VKtheftop thereof. When the ventilator is upset `andreversedwhen engaged in the 'win f'dow fra-me A as shownin'Figure 36,the can- "opy extensions 24 and 25 deflect the currents of air `upwardlyfrom Without vthe enclosure Ato the interior thereof asindica'ted by theaiaowifn :said 'Figure 6 of the draw-ing.
